Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container for packing a cylindrical article such as a coil wound with a film.

[0002]

[Prior art]

 For example, a metal deposition film for manufacturing a film capacitor is a thin plastic film on which metal such as Al or Zn is deposited, which is cut into a band having a width of several cm, and a cylindrical bobbin of the same width. The product is shipped in parallel wound around the outer circumference of.

Conventionally, a film winding coil of this kind is passed through a large number around a plastic pipe having a cylindrical shape having an outer diameter slightly smaller than the inner diameter of the bobbin and having a height of several tens of centimeters. It was placed in a plastic bag, decompressed, and then shipped in a box such as a cardboard box. Such a packing method is not limited to the coil, but is widely adopted for other cylindrical articles.

[0004]

[Problems to be solved by the device]

 By the way, in the above packaging structure, if the pipe should be deformed, it will hinder the work of passing the cylindrical article through the pipe.Therefore, it is necessary to make the pipe with a hard material that is difficult to deform. There was a drawback that the pipe was bulky. For this reason, the shipping destination of the film requires a space for storing the pipes until the time of return, and the load density at the time of return is low, and transportation costs are high.

Further, the pipe is expensive to form, and in order to support the cylindrical article by the pipe without rattling, the gap between the outer peripheral surface of the pipe and the inner peripheral surface of the article must be reduced. When pulling out the articles one by one from the pipe, it is necessary to grasp and lift the outer peripheral surface of the cylindrical article, and consideration must be given to protection of the outer peripheral surface so that workers can touch the outer peripheral surface in advance. It was

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and is composed of a pair of rectangular plate members having the same dimensions, and each plate member has a side from the center of one side to the other side. A slit is formed that extends toward the center of the inner peripheral support, and each plate is assembled into a cross shape by engaging the slits with each other. A pair of circular ring-shaped contact plates that support both ends of a cylindrical article row that is removably inserted into the outer periphery of the inner peripheral support and that has an outer diameter that is equal to or greater than the outer diameter of the cylindrical article. The inner peripheral support, the cylindrical article, and the respective contact plates are airtightly wrapped, and a plastic bag body whose inside pressure is reduced is provided.

[0007]

[Action]

 In the container for packaging the cylindrical article according to the present invention, since the inner peripheral support can be disassembled into two plates having the same shape, by disassembling these plates and stacking them in parallel, the storage capacity of the inner support can be increased. Can be made extremely small, and the transportation cost can be reduced by increasing the packing density during transportation.

Further, since the plate material forming the inner peripheral support has a simple rectangular shape, the molding cost is lower than that when the inner peripheral support is cylindrical, and the weight can be reduced. Furthermore, since the inner peripheral support has a cross-shaped cross section, there are four fan-shaped gaps between the inner peripheral surface of the article and the inner peripheral support in the state of supporting the cylindrical article. By inserting and supporting the inner peripheral surface of the article, the outer peripheral surface of the article can be inserted / removed without touching it.

【Example】

 1 to 3 are a perspective view, a vertical sectional view and a plan view showing an embodiment of a packaging container for a cylindrical article according to the present invention, respectively.

This packing container has an inner peripheral support body 1 in which two plate members 2 and 4 are assembled in a cross shape, and a pair of circular ring-shaped contact members vertically inserted into both end portions of the inner peripheral support body 1. A cylindrical article C to be packed is composed of a plate 6 and a bag body 10 that hermetically wraps the whole body. A large number of cylindrical articles C are inserted into the inner peripheral support body 1, and both ends of the row are in contact with each other. It is designed to be supported by the plate 6. The cylindrical article C of this example is a coil C in which a film F having the same width as the bobbin B is wound in parallel on the outer circumference of a cylindrical bobbin B.

Each of the plate members 2 and 4 of the inner peripheral support 1 has a height capable of inserting a predetermined number of coils C and a width slightly smaller than the inner diameter of the coil C (that is, the inner diameter of the bobbin B). It is desirable that the thickness of each of the plate members 2 and 4 is as thin as possible within a range in which the deformation of the inner peripheral support 1 can be prevented.

As shown in FIG. 4, each of the plate members 2 and 4 is provided with slits 2A and 4A extending from the center of one end thereof to the center in the height direction along the center line. The widths of the slits 2A and 4A are almost the same as the thicknesses of the plate members 2 and 4. By interlocking the slits 2A and 4A with each other, the plate members 2 and 4 are assembled in a cross shape without rattling. There is.

As the material of the plate members 2 and 4, hard and lightweight plastic is suitable, but other lightweight materials such as aluminum and ceramics may be used if necessary. In this example, the slits 2A and 4A have the same total length, but it is also possible to lengthen one and shorten the other.

As shown in FIG. 3, the inner diameter of the insertion hole 6 A formed in the center of each contact plate 6 is set to be slightly larger than the width of the plate members 2 and 4, and the outer diameter of the contact plate 6 is equal to that of the coil. It is set to be approximately the same as or slightly larger than the outer diameter of C. The material of the contact plate 6 is not limited, but various plastics, aluminum, ceramics, etc. are suitable in terms of strength.

Further, in this embodiment, as shown in FIG. 2, an annular sheet 8 made of polyurethane foam or the like is sandwiched between every other coil C. The outer diameter of these sheets 8 is larger than that of the coil C, and the inner diameter thereof is the same as that of the coil C. If the sheet 8 is sandwiched as described above, damage due to contact between the coils C can be prevented, but it is not always necessary to provide the sheet.

The bag body 10 is formed of a flexible plastic film, and as a concrete material, for example, a single product such as polyethylene or polypropylene, or a product obtained by coating these with polyvinylidene chloride, or a combination thereof. Examples of such materials include laminated base materials. The inside of the bag 10 is decompressed after the coil is packed, and the opening is hermetically sealed. As a result, oxidation of the film F is prevented, and the bag body 10 uniformly tightens the inner peripheral support body 1, the coil C and the respective contact plates 6, so that the coil C and the contact plate 6 are separated from the inner peripheral support body 1. It is prevented from coming off. Although not shown, the entire packaging container may be put in a cardboard box or the like for shipment.

According to the packaging container having the above structure, the inner peripheral support 1 can be disassembled into the two plate members 2 and 4. Therefore, by disassembling these plate members 2 and 4 and stacking them in parallel, The storage volume of the body 1 can be made extremely small, and the loading density during transportation can be increased to reduce the transportation cost. Further, since the plate members 2 and 4 have a simple rectangular shape, the molding cost is lower than when the inner peripheral support is cylindrical.

Further, since the inner peripheral support member 1 has a cross-shaped cross section, four fan-shaped members are provided between the inner peripheral surface of the coil C and the inner peripheral support member 1 in a state where a large number of coils C are supported. There is a gap between the bobbin B and the inner peripheral surface of the bobbin B can be supported. Therefore, there is also an advantage that the coil C can be inserted / removed without touching the outer peripheral surface of the coil C.

As shown in FIG. 4, openings 2B and 4B may be formed on both sides of the slits 2A and 4A of the plate members 2 and 4, respectively. The size of each of the openings 2B and 4B is such that a worker can easily insert his / her finger. If such an opening is formed, when the inner peripheral support 1 is taken out, fingers are inserted into both openings 2B of the plate material (2 in the figure) whose slit is open upward, so that the entire inner peripheral support 1 is removed. Can be easily lifted. Therefore, even when wearing gloves that are slippery, the inner peripheral support 1 can be easily attached and detached.

Further, the packaging container of the present invention is not applied only to the coil C, and can be used for packaging any article as long as it has a cylindrical shape.

[0021]

[Effect of device]

 As described above, according to the packaging container for a cylindrical article of the present invention, the inner peripheral support can be disassembled into two plate members having the same shape. Therefore, by disassembling these plate members and stacking them in parallel. In addition, the storage capacity of the inner peripheral support can be made extremely small, and the packing density during transportation can be increased to reduce the transportation cost. Further, since the plate material forming the inner peripheral support is a simple rectangular shape, the molding cost is lower than that when the inner peripheral support is cylindrical, and the weight can be reduced.

Further, since the inner peripheral support has a cross-shaped cross section, four fan-shaped gaps are formed between the inner peripheral surface of the article and the inner peripheral support in a state where the cylindrical article is supported, By inserting a hand into these gaps and supporting the inner peripheral surface of the article, there is an advantage that the outer peripheral surface of the article can be inserted and removed without touching it.
